Well its origins are discussed in part 1 which you should read if you haven't, since historically, even China dismissed it as rubbish and all the scholars they had pointed out that it didn't work hundreds of years ago.

Any success we've had with it since Mao used it for political gain has been entirely circumstantial. I can't say to understand martial arts to any degree but I can guarantee their intuitive ability to understand problems of posture comes from years of experience and knowledge of the physical body and its sensitive spots in general, rather than being spiritually connected with qi spots and meridian pathways.

If there's no evidence of these things, and any claim to use them to our benefit is proven false time and time again, or there is some slight benefit that is circumstantial with better results coming from alternative methods and even sham acupuncture, I don't see any reason to keep it alive. The fact that the effects can be replicated without even using the qi locations is one of the bigger nails in its coffin.

I'm still a little confused on what your stance on it is, to be honest, but the research has to be considered with these things no matter what one's position may be
